Research Frontiers In Magneto Chemistry


Book Description

Over the past 25 years, there have been many advances in the understanding of magnetic phenomena in molecular systems. For example, a variety of low-dimensional materials, and many new ferromagnetic, antiferromagnetic, and ferrimagnetic systems have been synthesized and analyzed; metal cluster compounds that exhibit magnetic exchange have been examined; new orbital overlap theories have been proposed to explain magneto-structural correlations in exchange coupled systems; and efforts directed toward the preparation of an organic ferromagnetic material have produced new and interesting compounds. There have also been many advances in the use of magnetism as a probe of inorganic biomolecules.This volume brings together reviews of current research in magnetochemistry that are written by the world's leading researchers in the fields of chemistry, physics, materials science, and magnetism. It contains comprehensive and in-depth reviews that describe some of the current activities of these scientists and their research and lays the foundation for future research endeavors.

Synthesis of Physico-Chemical Properties of Metal Oximes, Hydrazones and Semicarbazones


Book Description

The most amazing field of modern inorganic chemistry is co-ordination chemistry. From last four decades, co-ordination chemistry created its own identity in the Inorganic chemistry. The co-ordinate compounds also referred as complexes is a combination of ligand or chelating agent with metal ions through co-ordinate bonds. Ligands are covalent bonded organic molecules containing lone pair or lone pairs of electrons on heteroatom in the organic moiety. As metal ions are electron deficient so these form co-ordinate bonding between metal ion and ligand. The behaviour of metal ion with different ligands depends upon the sterric hindrance, structure, various substituent and nature of bonding present in ligands as well as screening effect, Kernal effect, atomic number oxidation state of metal ion. It was also observed in complexes that there are primary as well as secondary valencies.




Frontiers of High Pressure Research II: Application of High Pressure to Low-Dimensional Novel Electronic Materials


Book Description

In recent interactions with industrial companies it became quite obvious, that the search for new materials with strong anisotropic properties are of paramount importance for the development of new advanced electronic and magnetic devices. The questions concerning the tailoring of materials with large anisotropic electrical and thermal conductivity were asked over and over again. It became also quite clear that the chance to answer these questions and to find new materials which have these desired properties would demand close collaborations between scientists from different fields. Modem techniques ofcontrolled materials synthesis and advances in measurement and modeling have made clear that multiscale complexity is intrinsic to complex electronic materials, both organic and inorganic. A unified approach to classes of these materials is urgently needed, requiring interdisciplinary input from chemistry, materials science, and solid state physics. Only in this way can they be controlled and exploited for increasingly stringent demands oftechnology. The spatial and temporal complexity is driven by strong, often competing couplings between spin, charge and lattice degrees offreedom, which determine structure-function relationships. The nature of these couplings is a sensitive function of electron-electron, electron-lattice, and spin-lattice interactions; noise and disorder, external fields (magnetic, optical, pressure, etc. ), and dimensionality. In particular, these physical influences control broken-symmetry ground states (charge and spin ordered, ferroelectric, superconducting), metal-insulator transitions, and excitations with respect to broken-symmetries created by chemical- or photo-doping, especially in the form of polaronic or excitonic self-trapping.

Handbook on the Physics and Chemistry of Rare Earths


Book Description

This volume of the Handbook adds five new chapters to the science of rare earths. Two of the chapters deal with intermetallic compounds. An overview of ternary systems containing rare earths, transition metals and indium - Chapter 218 - opens the volume. It is followed by Chapter 219 sorting out relationships between superconductivity and magnetism. The next two chapters are dedicated to complex compounds of rare earths: Chapter 220 describes structural studies using circularly polarized luminescence spectroscopy of lanthanide systems, while Chapter 221 examines rare-earth metal-organic frameworks, also known as coordination polymers. The final Chapter 222 deals with the catalytic activity of rare earths in site-selective hydrolysis of DNA and RNA. Ya. Kalychak, V. Zaremba, R. Pöttgen, M. Lukachuk, and R.-D. Hoffmann review the synthesis conditions, isothermal sections of phase diagrams, crystallography and basic physical properties of ternary intermetallic compounds consisting of the rare-earth metals, transition metals and indium. P. Thalmeier and G. Zwicknagl revisit the last decade of research uncovering some of the mysteries of the superconducting state, especially those related to heavy fermion superconductivity and the co-existence of the superconducting and exotic magnetically ordered states. J. P. Riehl and G. Muller review how the molecular stereochemistry of lanthanide complexes both in pure forms and in mixtures can be probed using circularly polarized luminescence. O. Guillou and C. Daiguebonne assess rare earth-containing metal-organic frameworks, also known as coordination polymers, which hold a potential as working bodies for opto-electronic and magnetic devices, microporous materials for a variety of uses, such as size- and shape-selective separations, catalyst support and hydrogen storage materials. Concluding the volume, M. Komiyama argues that future biotechnology may well rely on the use of rare-earth ions as unique catalysts that can slice DNA and RNA in order to allow their reprogramming, and thus lead to more effective bioengineered processes.
